This includes, when relevant, documentation of a b c d the machinery for which the risk assessment has been made for example, specifications, limits, intended use ; any relevant assumptions that have been made loads, strengths, safety factors, etc. When carrying out a risk assessment, the risk from the most likely dn of the harm that is likely to occur from each identified hazard shall be considered, but the highest foreseeable severity shall also be taken into account, even if the probability of such an occurrence is not high.

EXAMPLE A fixed guard preventing access to a zone where a mechanical hazard is present used to reduce noise levels and collect toxic emissions.

Subclause of this International Standard 6. Another fundamental concept that is introduced in Clause 5. This second edition cancels and replaces ISO The continued operation of the safety functions is essential for the safe use of the machine. Electrical hazards Ba the design of the electrical equipment of machines, Iwo gives general provisions about disconnection and switching of electrical circuits and for protection against electric shock.

Compliance with this document provides one means of conforming with the specific essential requirements of the Directive concerned and associated EFTA regulations. They shall be designed to prevent hazards due to unintended opening.

Then, other measures should be applied to achieve the same level of confidence for the stopping or slowing down. It is essential that these signals a b be emitted before the occurrence of the hazardous event, be unambiguous, 46? At least the following requirements shall be met: It is recommended that this standard be incorporated in training courses and manuals to convey basic terminology and general design methods to designers.


Materials and substances or physical factors temperature, noise, vibration, radiation and environment? Mechanization can be achieved, e. When protective measures include work organization, correct behaviour, attention, application of personal protective equipment PPEskill or training, the relatively low reliability of such measures compared with proven technical protective measures shall be taken into account in the risk estimation.

Basic concepts, general principles for design. While the foregoing discusses the body of Part 1 of the standard, there are also some additional information included.

Human interactions with displays and control actuators [30] ISOErgonomic principles related to mental work-load – General terms and definitions [31] ISOErgonomic principles related to mental workload – Part 2: Once this standard is cited in the Official Journal of the European Union under that Directive and has been implemented as ne national standard in at least one Member State, compliance with the normative clauses of this standard confers, within the limits of the scope of this standard, a presumption of conformity with the relevant Essential Requirements of that Directive and associated EFTA regulations.

Examples of hazards are given in Annex B.

Safety of machinery: EN ISO 12100-1 and EN ISO 12100-2

The selector may be replaced by another selection means which restricts the use of certain functions of the machinery to certain categories of operators for example, access codes for certain numerically controlled functions. Tables should be adjacent to the relevant text. Tables should be adjacent to 1210-2 relevant text. If safe operation requires controls to be situated outside the carrier, the operator in the carrier shall uso provided with the means of preventing hazardous movements.

The eh for use shall be given in the language s of the country in which the machine will be used for the first time and in the original version. For dated references, only the edition cited applies. The order of potential consequences is not associated with any priority.


The design of enclosed work stations, such as cabs and cabins, shall take into account ergonomic principles concerning visibility, lighting, atmospheric conditions, access, posture. The continued operation of the safety functions is essential for the safe use of the machine. Components vs be selected taking into account all factors mentioned above see also 6.

Safety distances to prevent hazard zones being reached by upper and lower limbs. Risk analysis provides information required for the risk evaluation, which in turn allows judgments to be made about whether or not risk reduction is required. Applying principle of positive mechanical action 6.

This is particularly important when remote access for diagnostic or process correction purposes is required. The correct design of machine control systems can avoid unforeseen and potentially hazardous machine behaviour.

Safety-related components for example, certain sensors of known reliability shall be used. The programmable electronic control system should be installed and validated to ensure that the specified performance [for example, safety integrity level SIL in IEC ] for each safety function has been achieved.

This reset shall be possible only at that location where the emergency stop command has been initiated. See Figure 4 and ISO Durability and availability of the documents: Hazardous event Contact enn rough surfaces Contact with sharp edges and corners, protruding parts Contact with moving parts Contact with rotating open ends 6.

NOTE 2 Adequate protective measures associated with each of the operating modes and intervention procedures reduce the possibility of operators being induced to use bss intervention techniques in case of technical difficulties. The use of colours should be considered, particularly in relation to components requiring quick identification. Constraints due to the necessary or foreseeable use of personal protective b such as footwear, gloves ieo be taken into account.
